an international team of astrophysicists has recorded a powerful gamma-ray burst from an unusual space object QSO B0218+357. A beam of high-energy particles due to the curvature of space-time is divided into two parts, which collided with our planet with a difference of 10-12 days. Their findings are presented in an article published in the journal Astronomy&Astrophysics.

When the supernova will destroy life on Earth
QSO B0218+357 is a blazar, the distance from which the Earth is estimated at seven billion light-years. This is a rare type of quasars — the brightest objects in the Universe that formed supermassive black hole and absorb it substance. They are assumed to represent nuclei of active galaxies. However, blazey differ in that they are very compact, and their brightness changed periodically. Like other quasars, they emit jets of plasma (jets) at a speed close to the speed of light.
In July 2014, scientists have discovered that QSO B0218+357 was a powerful flash. It failed to register with the space Observatory Fermi-LAT and Cherenkov telescope MAGIC, designed for the detection of particles generated by the collision of gamma rays with Earth’s atmosphere. The energy of the photons that have reached our planet, reached values 65-175 GeV.
As between the blazar and Earth is a massive object that distorts its gravitational field in space-time, the rays from QSO B0218+357 crashed into two beams, and one of them came 10-12 days after the second. This phenomenon is called gravitational lensing.
According to astrophysicists, at the moment of QSO blazar B0218+357 is the most remote gamma ray source known.
